It is given that the molar mass of A solvent = 64.9 g/mol , normal boiling point =139.6 oC. The boiling point elevation constant, K b , for this solvent = 1.73 oC/m. Determine the boiling point of the solution If 11.9 grams of a nonelectrolyte with molar mass = 30.5 g/mol are combined with 200.0 grams of the solvent,?
